Abstract EN
With advancement in the field of structural engineering, hunt for smarter materials has channelised the research towards the application of composite material.
It is the high specific weight and specific stiffness of this material that have drawn the interest of different industrial sectors.
Civil engineers also picked up composites to use it as a roofing material.
Laminated composite shells, which can cover large column-free area and reduces dead weight of structure, show vulnerability under sudden impact due to their low transverse shear resistances.
This study utilises finite element tool to investigate the dynamic response of a multilayered laminated composite hypar shells for fully clamped boundary condition.
This class of shells is unique in a sense that the curvature has only the radius of cross curvature and these shells do not admit easy closed form solution particularly when the boundary conditions are complicated.
Contact behavior of impactor and impacted mass has been modeled by modified Hertzian contact law and time-dependent equations are solved using Newmark’s time integration technique.
Basic aim is to analyse the shell for symmetrically placed multilayered angle and cross ply lamination under different impact velocities.
